l I, nmmscesenoie, tragedy of Philadelphia, ein the StatefofPennsylvaniahave invented certain `"Improvements inthcApparatns forFacilitating the Starting ofHorse-Carson Railways, of which the fol-:lowing is aspecication. l i l,

` Nature aotdlQbj'ects of the Iiweatio-it.

My invention relates tothe construction and arrangement of certainlrack-bars,eccentric swinging "bars, slotted guides, and retractingcordsor chains, to operate,in combination Withfthe bottom frame, shafts,

`or pole, wheels,vaud `jbralri ng-lever of a'czu', substanl f tially ashereinafter ydescribed and `set forth 5 .the object `of my inventionbeing'to'enable thevdriver to readily applythe `tractile pow'erjof`thefll'orses near `to, the

upper parts of the rims ofall thewheels at once in fstarti'ng thecarforward,and'also to enable hirn to retract the said rackfbars withfacility in the operation. e of brakingthe wheels total-rest the forwardmotion of VDesezription of Dra/Loring.

e lnL,Genrel1)escr&9t5tl 'A The rack-bars are'farranged parallel to eachother `and tothe side sills B` B of the car, so as to be directlyabovethe teethor-cogs C C, n the inner sides bar there is alseries ofnotchesor lserrated teeth, a",

and below cach `series theratchet-toothed or notched e eccentric leverD` swings freely in such a manuel: that l I itslteeth `or notches areborneupward by its weighted endd.` i

, Between the teeth a', at `the forward end of each o the rack-bars, andthe serrated teeth af', there is a projection, which comes in contactwith and slips up V The Schedulerefened to injthese Lettera Patent andmaking part of the same.

upon a stationary block, a4, which is fixed to the frame at apoint nearthe forward wheel, and thus raises up Ithe rack-bar when the said barsare being drawn backward toward their inoperative position.

, The ratchet-toothed eccentric levers D D are eachv constructed andapplied 4so that, as the rack-bars are being drawn backward, the teetha," a, catch first in the highest tooth of the levers D D and then. inthe succeeding teeth, and in this manner thev said rack bars are raisedupward bythe said eccentric levers D D fai' enough to free theirteeth,c' a', entirely from the" ebgs O G ofthe wheels, (see dottedlinesin ng. 1.)4

The teeth of the levers D D having passed ont of contact with the teetha a of the rack-bars A A, the

said levers D D fall over rearward, and remain suspended loosely ontheir fulcrums Auntil the rack-bars A A, on being drawn forward to pullthe` wheels around, slidev over them, as represented bythe full lines ing. 1.

, The slotted guide or guides E- Eare pivoted securely to the front endofthe hoor-frame of the cai-,and the pole or shafts F, with their doubleor single-tree, j" f', attached, slide in the said slotted guide orguides, respectively,the ends of the single or doubletree being.respectively connected with the for-Ward ends of the two rack-bars A Aby means of suitable chains or ropes cf e', of such lengths that, whenthe pole or shafts.

` are drawn near tothe outer end of the slot or slots in E, the saidrack-bars will be in the position represented in iig. 3 and when thesaid pole or shafts are slipped back to the rear end of said slots, theraclcbars can be drawn back (as'will be explained) to the posi- Y tionshown by the .full lines in lig.' 1.

l For the purpose of enabling thel driver to retract the rack-bars A A,an additional pulley, G, isxed on the lower end of the shaft of theusual braking handlever, and from this pulley G a chain or rope,`g', andsliding bar g, extend back to two chains g,l which, guided by pulleys,connect with the respective rear ends of the said rack-bars A A, asshown in fig. 2, so that the driver, in operating the braking-lever,causes, at the same time, the said rack-bars to he drawn back into theirinoperative positions, (see lig. l.)

It willv be understood without further description that, when the horsesare'started, the rackfbars A A will be drawn forward, causing theirteeth a' to catch in the cogs C" G neartheupper part of the rims of allthe wheels at once, and thus simultaneously rotate thel wheels or starta loaded car forward without straining the horses,- as heretofore, orwith much less effort than' if the draft was made directly from theaxles'of the wheels; and that an inequality in the burden of therespectiveA ends of the carf at any time will not,

canse any difference in the amount of power required i swinging levers DD, the stationary block a4, the to start the ear, because all the wheelsare operated slotted guides E E, pole ol' shafts F, and chains or uponat the same time by the rack-bars. ropes e e', the pulley G ou thebraking-lever, chain or It will also be seen that the rack-bars areretracted rope g, bar g, and chains or ropes g", the said parts by thedriver in braking the wheels, and tha-t the said being constructed andarranged to operate in combi-- bars are, at the same time, liftedentirely clear of the nation with the bottom frame and the four wheelsof eogs in the wheels, so as to prevent any rattling, noise, the car,substantially as and for the purpose hereinor friction with the saidwheels. i before set forth and described.
